Trail 100 Andorra by UTMB transforms the tiny principality into a multi day mountain festival, sending runners from the Ordino valley across some of the highest and most spectacular terrain in the Pyrenees. With distances from 10 to 105 km and relentless climbing above 2,000 metres, this race rewards strong legs, sharp navigation and a deep love of high mountain running.
Trail 100 Andorra by UTMB is a pure high mountain race. Set in the Pyrenees, the event takes over the parish of Ordino and launches runners into a vertical world of rocky ridges, pine forests, alpine meadows and glacial lakes. The Ultra 105K traces a full loop around the principality, crossing passes and summits that rarely dip below 2,000 metres, while shorter distances of 80, 50, 21 and 10 km offer scaled versions of the same dramatic terrain.
The landscape is what sets this race apart. Andorra packs an extraordinary amount of vertical relief into a small footprint, meaning the trails climb and descend with little respite. Runners on the Ultra face nearly 6,900 metres of positive elevation gain, navigating exposed cols and technical descents that demand both fitness and mountain craft. The reward is a succession of panoramic vistas over the Pyrenean chain that feel earned in every sense.
As part of the UTMB World Series, Trail 100 Andorra offers Running Stones and has quickly become a coveted target for trail runners seeking a genuine high altitude challenge in southern Europe. The race village in Ordino brings together athletes from across the globe in a warm, festival atmosphere, with the mountains always looming just above.
